[Transdisciplinary treatment of functional movement disorders: integration instead of dissociation].

Successful treatment of patients with functional motor disorders is integrative in several ways: the primary treatment goal is the (re)integration of sensorimotor, cognitive and social functioning. The prerequisites for this are an integrated biopsychosocial model of everyone involved as well as close transdisciplinary cooperation. Instead of a simple addition of treatment components, all care providers and patients act in concert.

Functional neurological symptoms are a frequent and relevant comorbidity in patients with multiple sclerosis.

Introduction: Functional neurological symptoms (FNS) in multiple sclerosis (MS) have shown to be underinvestigated even though neurological diseases such as MS represent a risk factor for developing FNS. Comorbidity of FNS and MS can produce high personal and social costs since FNS patients have high healthcare utilization costs and a quality of life at least as impaired as in patients with disorders with underlying structural pathology. This study aims to assess comorbid FNS in patients with MS (pwMS) and investigate whether FNS in pwMS are associated with poorer health-related quality of life and work ability.

Prevalence of medically induced psychological trauma and its influence on women's health.

Objective: The aim of the present study was three-fold. One, to assess the prevalence of medical traumatization in outpatients of a gynecologic department; two, to analyze the relationship of medical traumatization with adverse childhood events; and three, to investigate the extent to which medical traumatization affects the health outcomes of woman.

Methods: Between January and September 2022, a prospective cross-sectional study recruited patients of a gynecologic outpatient clinic at St.

Association of Fatigue Severity With Maladaptive Coping in Multiple Sclerosis: A Data-Driven Psychodynamic Perspective.

Fatigue in persons with multiple sclerosis (PwMS) is severely disabling. However, the underlying mechanisms remain incompletely understood. Recent research suggests a link to early childhood adversities and psychological trait variables.

Increased Amygdala Activity Associated With Cognitive Reappraisal Strategy in Functional Neurologic Disorder.

Cognitive reappraisal is an emotion regulation strategy to reduce the impact of affective stimuli. This regulation could be incomplete in patients with functional neurologic disorder (FND) resulting in an overflowing emotional stimulation perpetuating symptoms in FND patients. Here we employed functional MRI to study cognitive reappraisal in FND.

Fatigue in Multiple Sclerosis Is Associated With Childhood Adversities.

Fatigue is a common and disabling symptom in patients with Multiple Sclerosis (PwMS). Its pathogenesis, however, is still not fully understood. Potential psychological roots, in particular, have received little attention to date.

The relation between memory and decision-making in multiple sclerosis patients.

Background: Impairments in long-term and working memory are widespread in Multiple Sclerosis (MS), setting on in early disease stages. These memory impairments may limit patients' ability to take informed and competent medical decisions, too. In healthy populations, memory abilities predict decision quality across a wide range of tasks.

Validating Sclerotinia sclerotiorum Apothecial Models to Predict Sclerotinia Stem Rot in Soybean (Glycine max) Fields.

In soybean, Sclerotinia sclerotiorum apothecia are the sources of primary inoculum (ascospores) critical for Sclerotinia stem rot (SSR) development. We recently developed logistic regression models to predict the presence of apothecia in irrigated and nonirrigated soybean fields. In 2017, small-plot trials were established to validate two weather-based models (one for irrigated fields and one for nonirrigated fields) to predict SSR development.

Variation of Functional Neurological Symptoms and Emotion Regulation with Time.

Introduction: The present study addressed the variation of emotion regulation in the context of functional neurological symptom disorder (FNSD) by examining changes of functional neurological symptoms (FNS), general psychological strain, alexithymia, emotion regulation strategies, and cortical correlates of emotion regulation in the context of a standard inpatient treatment program.

Methods And Materials: Self-report data on FNS, general psychological strain, alexithymia, emotion regulation strategies, and cortical correlates of an experimentally induced emotion regulation task (participants either passively watched unpleasant and neutral pictures or regulated their emotional response to unpleasant pictures using pre-trained reappraisal, while an electroencephalogram was recorded) were compared between 19 patients with FNSD and 19 healthy comparison participants (HC) before and after a 4-week standard treatment protocol that included a combination of (individual and group) psychotherapies and functional treatments (such as physiotherapy) or a 4-week interval in HC, respectively.

Results: General psychological strain did not decrease significantly in FNSD patients.

Symptom-specific amygdala hyperactivity modulates motor control network in conversion disorder.

Initial historical accounts as well as recent data suggest that emotion processing is dysfunctional in conversion disorder patients and that this alteration may be the pathomechanistic neurocognitive basis for symptoms in conversion disorder. However, to date evidence of direct interaction of altered negative emotion processing with motor control networks in conversion disorder is still lacking. To specifically study the neural correlates of emotion processing interacting with motor networks we used a task combining emotional and sensorimotor stimuli both separately as well as simultaneously during functional magnetic resonance imaging in a well characterized group of 13 conversion disorder patients with functional hemiparesis and 19 demographically matched healthy controls.

Functional neurological symptoms modulate processing of emotionally salient stimuli.

Objective: Dysfunctional emotion processing has been discussed as a contributing factor to functional neurological symptoms (FNS) in the context of conversion disorder, and refers to blunted recognition and the expression of one's own feelings. However, the emotion processing components characteristic for FNS and/or relevant for conversion remain to be specified. With this goal, the present study targeted the initial, automatic discrimination of emotionally salient stimuli.

Functional networks of motor inhibition in conversion disorder patients and feigning subjects.

The neural correlates of motor inhibition leading to paresis in conversion disorder are not well known. The key question is whether they are different of those of normal subjects feigning the symptoms. Thirteen conversion disorder patients with hemiparesis and twelve healthy controls were investigated using functional magnetic resonance tomography under conditions of passive motor stimulation of the paretic/feigned paretic and the non-paretic hand.

Emotion regulation and functional neurological symptoms: Does emotion processing convert into sensorimotor activity?

Objective: Functional neurological symptoms (FNS) are hypothetically explained as a shift of emotion processing to sensorimotor deficits, but psychophysiological evidence supporting this hypothesis is scarce. The present study measured neuromagnetic and somatic sensation during emotion regulation to examine frontocortical and sensorimotor activity as signals of altered emotion processing.

Methods: Magnetoencephalographic (MEG) activity was mapped during an emotion regulation task in 20 patients with FNS and 20 healthy comparison participants (HC).

"That pulled the rug out from under my feet!" - adverse experiences and altered emotion processing in patients with functional neurological symptoms compared to healthy comparison subjects.

Background: Medically unexplained movement or sensibility disorders, recently defined in DSM-5 as functional neurological symptoms (FNS), are still insufficiently understood. Stress and trauma have been addressed as relevant factors in FNS genesis. Altered emotion processing has been discussed.

Neural correlates of hysterical blindness.

The neural mechanisms underlying conversion disorders such as hysterical blindness are at present unknown. Typically, patients are diagnosed through exclusion of neurological disease and the absence of pathologic neurophysiological diagnostic findings. Here, we investigate the neural basis of this disorder by combining electrophysiological (event-related potentials) and hemodynamic measures (functional magnet resonance tomography) in a patient with hysterical blindness before and after successful treatment.

Motor excitability during movement imagination and movement observation in psychogenic lower limb paresis.

Background: Patients with a psychogenic paresis have difficulties performing voluntary movements. Typically, diagnostic interventions are normal. We tested whether patients with a psychogenic lower limb paresis exhibit abnormal motor excitability during motor imagery or movement observation.

Abnormal motor excitability in patients with psychogenic paresis. A TMS study.

Background: Patients with motor conversion disorders present an inability to execute movements voluntarily, although central and peripheral motor pathways are normal. We speculated that this phenomenon could be due to an abnormal loss of excitatory drive on central motor areas.

Methods: The effect of motor imagery on motor excitability was tested in a group of eight patients with a functional (psychogenic) hemiparesis and in an age-matched control group (n=8) by using transcranial magnetic stimulation (TMS).

Electrophysiological correlates of motor conversion disorder.

In patients with a functional (psychogenic) paresis, motor conduction tests are, by definition, normal. We investigated whether these patients exhibit an abnormal motor excitability. Four female patients with a functional paresis of the left upper extremity were studied using transcranial magnetic stimulation (TMS).

Conversion disorder revisited.

Conversion disorder is defined as a psychiatric illness whose symptoms or deficits, affecting voluntary motor or sensory function, cannot be explained by a neurological or general medical condition. Proposing a strategy in the search for the neural mechanisms underlying conversion disorder is a difficult task, partly because key features of the illness inherently lie on a continuum with other psychiatric disorders, such as depression and posttraumatic stress disorder. Recent brain imaging studies have revealed neural circuits involved in complex mental processes potentially related to conversion disorder.

Posttraumatic Stress Disorder in patients with traumatic brain injury.

Background: Severe traumatic stressors such as war, rape, or life-threatening accidents can result in a debilitating psychopathological development conceptualised as Posttraumatic Stress Disorder (PTSD). Pathological memory formation during an alarm response may set the precondition for PTSD to occur. If true, a lack of memory formation by extended unconsciousness in the course of the traumatic experience should preclude PTSD.
